Robust semi-regular mesh representation of 3D dynamic objects

In this paper, we propose a robust scheme to represent 3D dynamic objects, which are given as a sequence of irregular meshes. The sequence of irregular meshes is converted into a sequence of semi-regular meshes with time-invariant topology to facilitate the manipulation of 3D data. To this end, we sequentially perform the motion estimation of base meshes, the shape transformation of subdivision points, and the selective intra-remeshing. It is shown that a given sequence can be efficiently remeshed without parameterization data by exploiting temporal correlation in the sequence. Simulation results demonstrate that the proposed algorithm reproduces the original geometry faithfully with a sequence of semi-regular meshes.
